Currently, "Present Windows in Current Workspace" zooms the windows nicely if there is more than one window per screen. If there is only one per screen, it doesn't zoom the windows out at all but dims the one that's not under the pointer slightly. If possible, I'd like the windows to get zoomed slightly so that a little bit of desktop can be seen (e.g. see Gnome's implementation). This can be optional, and off by default. The main reason for this is that it's not always clear that the effect has taken hold as the visual cues are too small.

I'd also like this as a tie-in to my other feature request (viewtopic.php?f=66&t=156974) which, together with this one, would make KDE/Plasma really sweet to use.
